Hi,
I have a 18m DS and a 2yo niece who see each other probably 3 times a week. They get very excited when they see each other, but their playing usually descends into snatching each others toys and hitting each other. They both also seem to get jealous if for example I'm cuddling one or if one of them is eating something (even if they are both eating the same thing!)
I'm just seeing if anyone had any advice on how to deal with this behaviour before it gets out of hand.
